Description

La présente invention concerne un dispositif de fixation de verres supplémentaires sur des lunettes.The present invention relates to a device for fixing extra glasses on glasses.

Ces dispositifs sont le plus souvent utilisés pour monter des verres filtrants (verres de protection contre le rayonnement solaire) sur des lunettes à verres correcteurs et sont en général d'un type standard qui ne correspond pas à la monture des lunettes. Ils sont de plus équipés de verres qui n'ont pas la forme des verres correcteurs des lunettes, de sorte que l'ensemble formé du dispositif à verres filtrants et des lunettes à verres correcteurs est plutôt lourd, encombrant et peu esthétique. En outre, ces dispositifs connus comportent des moyens d'accrochage sur les lunettes, qui sont plus ou moins bien adaptés à la monture des lunettes.These devices are most often used to mount filter glasses (glasses of protection against solar radiation) on glasses with corrective lenses and are usually of a standard type that does not match the mount of glasses. They are also equipped with glasses that do not have the shape of corrective lenses glasses, so that the whole formed the device with filtering glasses and glasses correctors is rather heavy, cumbersome and aesthetic. In addition, these known devices have hooking means on the glasses, which are more or less well adapted to the mount of glasses.

On a déjà proposé, dans le brevet US 5 920 370, un dispositif de ce type qui est formé d'un pont en matière flexible et de deux supports également en matière flexible qui sont fixés par des vis sur le pont. Des fils de nylon sont fixés ou accrochés sur les supports pour le montage des verres sur les supports. Des crochets sont également montés par des vis sur les supports pour la fixation du dispositif sur des lunettes. Ce dispositif s'adapte mieux à la forme de la monture des lunettes, grâce à la flexibilité du pont et des supports, mais sa fabrication et son assemblage sont relativement complexes, longs et coûteux, en raison des fixations par vis des crochets et des supports. It has already been proposed, in US Pat. No. 5,920,370, a device of this type which is formed of a bridge in flexible material and two supports also in flexible material that are fixed by screws on the bridge. Nylon threads are attached or hung on supports for mounting glasses on supports. Hooks are also mounted by screw on the brackets for fixing the device on glasses. This device adapts better to the shape of the spectacle frame, thanks to the flexibility of the bridge and supports, but its manufacture and its assembly are relatively complex, long and expensive, because of the bindings by screws hooks and brackets.

Le document DE-A-196 04 790 décrit un dispositif de fixation de verres supplémentaires conforme au préambule de la revendication 1. Les deux branches supportant les verres supplémentaires ne sont pas reliées par un pont (au sens usuel de ce terme), mais par une série de cinq branches formant un U vertical et un U horizontal.DE-A-196 04 790 discloses a device additional lens fixing in accordance with preamble of claim 1. The two branches supporting the extra glasses are not connected by a bridge (in the usual sense of that term), but by a series of five branches forming a vertical U and a horizontal U.

Le U horizontal sert de moyens d'accrochage sur les verres de lunettes.The horizontal U serves as hooking means on glasses of glasses.

Selon le DE-A-196 04 790, les moyens de liaison entre les verres supplémentaires comprennent trois branches formant l'étrier d'accrochage horizontal en U sur le pont des lunettes, et deux branches qui partent de l'étrier et qui s'étendent vers le bas en oblique, le long des bords des verres des lunettes, et se terminent par des coudes reliés aux branches supportant les verres supplémentaires. Cette structure des moyens de liaison est complexe et donc coûteuse.According to DE-A-196 04 790, the connecting means between the extra glasses include three branches forming the horizontal stirrup in U on the glasses deck, and two branches that start from the stirrup and extend downwards oblique, along the edges of glasses glasses, and end with elbows connected to the branches supporting the extra glasses. This linkage structure is complex and therefore expensive.

Le dispositif selon le document DE-A-196 04 790 n'est pas adaptable automatiquement et sans modification à toutes les lunettes. Un opticien doit, avec une pince, modifier les coudes de l'étrier pour adapter la largeur de cet étrier à la longueur du pont des lunettes : si l'étrier est trop large, on ne peut le monter sur les lunettes et s'il est trop étroit, il devient visible et les branches vont s'appuyer sur le nez de la personne qui porte les lunettes et vont la gêner. D'ailleurs le document précité montre que la largueur de l'étrier correspond exactement à la longueur du pont des lunettes.The device according to DE-A-196 04 790 is not adaptable automatically and without modification to all the glasses. An optician must, with pliers, modify the elbows of the caliper to adapt the width of this stirrup to the length of the glasses bridge: if the stirrup is too wide, we do not can mount it on the glasses and if it is too narrow, it becomes visible and the branches go lean on the nose of the person wearing the glasses and will embarrass her. Besides the document mentioned above shows that the width of the stirrup corresponds exactly the length of the bridge of the glasses.

De plus, il faut aussi adapter la longueur des branches à la distance entre le pont des lunettes et les bords inférieurs des verres des lunettes ; sinon le montage est impossible. In addition, it is also necessary to adapt the length of branches at the distance between the glasses bridge and the lower edges of glasses glasses; if not editing is impossible.

L'invention a notamment pour but de simplifier la fabrication et l'assemblage d'un tel dispositif et donc d'en abaisser le coût.The purpose of the invention is in particular to simplify the manufacture and assembly of such a device and therefore to lower the cost.

Elle a également pour but de rendre un tel dispositif adaptable à tout type de lunette.It is also intended to make such a device adaptable to any type of telescope.

Elle propose à cet effet un dispositif de fixation de verres supplémentaires sur des lunettes, tel que défini dans la revendication 1.It proposes for this purpose a attaching additional glasses to glasses, as defined in claim 1.

Les caractéristiques du dispositif de l'invention simplifient beaucoup la structure de celui-ci, simplifient également sa fabrication et son assemblage, augmentent sa fiabilité et réduisent largement son prix de revient.The features of the device of the invention simplify a lot the structure of it, simplify also its manufacture and assembly, increase its reliability and greatly reduce its cost price.

En outre, la flexibilité du pont et des branches permet une bonne adaptation à la forme des verres et à la forme de la monture des lunettes.In addition, the flexibility of the bridge and branches allows a good adaptation to the shape of glasses and in the shape of the frame of the glasses.

Avantageusement, le pont et les branches flexibles sont réalisés d'une seule pièce par moulage, en particulier de matière plastique ou de métal.Advantageously, the bridge and the branches hoses are made in one piece by molding, in particular of plastics or metal.

Selon encore une autre caractéristique de l'invention, les moyens d'accrochage sont formés d'une seule pièce avec lesdites branches.According to yet another characteristic of the invention, the attachment means are formed in one piece with said branches.

Ainsi, une seule opération de moulage permet de réaliser un dispositif comprenant un pont, des branches de support des verres et des moyens d'accrochage, tels que des crochets flexibles, pour la fixation du dispositif sur des lunettes. Thus, a single molding operation makes it possible to realize a device comprising a bridge, support branches glasses and means hooks, such as flexible hooks, for fixing the device on glasses.

Selon encore une autre caractéristique de l'invention, au moins certains des moyens d'accrochage sont montés sur les fils souples de fixation des verres sur lesdites branches flexibles.According to yet another characteristic of the invention, at least some of the means are attached to the flexible wires of fixing the glasses on said flexible branches.

Avantageusement, ces moyens d'accrochage sont réglables en position, par coulissement sur les fils souples.Advantageously, these attachment means are adjustable in position, sliding on the wires Flexible.

Cela permet d'adapter le dispositif selon l'invention à toute forme de monture de lunettes.This makes it possible to adapt the device according to the invention to any form of spectacle frame.

De façon générale, le dispositif selon l'invention est extrêmement simple puisqu'il peut être réalisé en une seule pièce, il est léger, peu visible et peu encombrant et il est adaptable à tous les types de montures et de verres de lunettes.In general, the device according to the invention is extremely simple since it can be made in one piece, it is light, little visible and compact and it is adaptable to all types of frames and spectacle lenses.

The invention will be better understood and other characteristics, details and advantages thereof will appear more clearly on reading the description which follows, given by way of example with reference to the appended drawings in which:
  • Figures 1 and 2 are front and top views respectively of a first embodiment of a device according to the invention;

  • Figure 7 is a partial view on a larger scale of a hooking means of the device of Figure 6; and
  • FIG. 8 is a view from above of the attachment means of FIG. 7.

On se réfère d'abord aux figures 1 à 5 qui représentent un premier mode de réalisation de l'invention.We first refer to Figures 1 to 5 which represent a first embodiment of the invention.

Dans ces figures, le dispositif portant les verres supplémentaires, appelé "face" dans la technique, comprend un ensemble moulé d'une seule pièce, constitué d'un pont ou pontêt 10, de deux branches latérales 12 et de moyens 14 d'accrochage sur des lunettes, le pont 10 étant relié à ses extrémités à des parties médianes ou intermédiaires des pièces latérales 12 et les moyens d'accrochage étant des pattes incurvées orientées vers l'extérieur.In these figures, the device carrying the extra glasses, called "face" in the technical, includes a molded assembly of a single piece, consisting of a deck or deck 10, two side branches 12 and means 14 hooking glasses, the bridge 10 being connected to its ends to middle or intermediate parts lateral parts 12 and the attachment means being curved legs oriented towards outside.

Les branches latérales 12 forment des moyens de support de verres supplémentaires tels notamment que des verres filtrants de protection contre le rayonnement solaire, et elles sont initialement rectilignes ou incurvées en arc de cercle. Sur leur côté extérieur par rapport au pont 10, ces branches comprennent une série de saillies 16 destinées à s'emboíter dans la rainure périphérique d'un verre.The lateral branches 12 form means of support for additional glasses such as filtering glasses to protect against solar radiation, and they are initially rectilinear or curved in an arc. On their the outer side with respect to the bridge 10, these branches include a series of projections 16 intended to fit into the peripheral groove of a glass.

A leurs extrémités, les branches 12 comprennent un ou deux trous 18 de passage d'un fil de nylon ou analogue destiné à être engagé dans la rainure périphérique 20 d'un verre 22 pour la fixation de ce verre sur la pièce 12.At their ends, the branches 12 comprise one or two holes 18 for passing a nylon thread or analog to be engaged in the groove device 20 of a glass 22 for fixing this glass on the room 12.

L'ensemble formé par le pont 10, les branches latérales 12 et les crochets 14 est moulé par exemple par injection en une matière plastique telle que du nylon ou analogue, ou éventuellement en métal. Les verres 22 destinés à être montés sur le face sont taillés à la même forme et aux mêmes dimensions que les verres des lunettes sur lesquelles le face doit être monté. Pour le montage des verres 22, on passe une extrémité d'un fil nylon dans un des trous 18 d'une branche latérale 12, on chauffe l'extrémité de ce fil pour former une boule retenant le fil et l'empêchant de ressortir par le trou 18, on place le verre sur la branche latérale 12 en engageant les saillies 16 dans la rainure périphérique du verre et en courbant la branche 12 pour l'adapter au contour du verre, on détermine la longueur nécessaire de fil de nylon, on engage l'autre extrémité de ce fil dans un trou 18 de l'autre extrémité de la branche 12, le verre étant retiré de la branche 12, et on chauffe l'autre extrémité du fil de nylon pour former une boule de retenue de ce fil dans le trou 18 correspondant. Ensuite, on monte le verre à l'intérieur du support formé par la branche 12 et le fil de nylon dont les extrémités sont fixées dans les trous 18 des extrémités de la branche 12, l'élasticité du fil de nylon et de la branche 12 permettant un montage serré du verre dans son support.The whole formed by the bridge 10, the branches side 12 and the hooks 14 is molded for example by injection into a plastic material such as nylon or the like, or possibly metal. The glasses 22 to be mounted on the face are cut to the same shape and dimensions the glasses of the glasses on which the face must to be mounted. For mounting lenses 22, we pass one end of a nylon thread in one of the holes 18 of a lateral branch 12, the end of this wire to form a ball retaining the wire and preventing it from coming out through the hole 18, we place the glass on the side branch 12 by engaging the protrusions 16 in the peripheral groove of the glass and by bending the branch 12 to adapt to the contour of glass, the necessary length of wire is determined of nylon, we engage the other end of this thread in a hole 18 of the other end of the branch 12, the glass being removed from the branch 12, and heating the other end of the nylon thread to form a retaining ball of this wire in the 18 hole corresponding. Then we go up the glass to inside the support formed by the branch 12 and the nylon thread whose ends are fixed in the holes 18 of the ends of the branch 12, the elasticity of nylon thread and branch 12 allowing a tight fitting of the glass in its support.

On procède de même avec le deuxième verre et la deuxième branche latérale 12.The same goes for the second glass and the second lateral branch 12.

Le face est alors prêt à être monté sur des lunettes, simplement en engageant les crochets 14 sur les verres ou sur la monture des lunettes.The face is then ready to be mounted on glasses, simply by engaging the hooks 14 on the glasses or on the frames of the glasses.

Dans ce mode de réalisation, les branches 12 sont appliquées sur les bords latéraux des verres 22 du côté du pont 10.In this embodiment, the branches 12 are applied on the side edges of the glasses 22 on the side of the bridge 10.

La forme et la dimension des verres 22 étant identiques à celles des verres des lunettes, le face monté sur les lunettes est très peu apparent et ne gêne pas la vision du porteur des lunettes. The shape and size of the glasses 22 being identical to those of glasses of the glasses, the face mounted on the glasses is very little apparent and does not do not disturb the vision of the wearer of the glasses.

Les extrémités du pont 10 peuvent être raccordées aux branches latérales 12, soit perpendiculairement à ces branches comme représenté en figure 3, soit sensiblement tangentiellement.The ends of the bridge 10 can be connected to the lateral branches 12, perpendicular to these branches as shown in Figure 3, substantially tangentially.

Le dispositif des figures 1 à 5 est adaptable à un grand nombre de montures de lunettes différentes, grâce à la flexibilité du pont 10 et des branches latérales 12.The device of FIGS. 1 to 5 is adaptable to a lot of different spectacle frames, thanks to the flexibility of bridge 10 and branches lateral 12.

La variante de réalisation représentée aux figures 6 à 8 présente l'avantage d'être universelle, c'est-à-dire adaptable à tous les types de montures, y compris les montures épaisses en matière plastique. Dans cette variante de réalisation, le pont 10 est de forme sensiblement rectiligne et s'étend au niveau du bord supérieur des verres 22 ou légèrement au-dessus de ce bord supérieur, et est raccordé à des branches latérales 12 qui entourent les verres 22 sur sensiblement la moitié de leur périphérie, sur le côté extérieur ou côté à l'opposé du pont 10 comme représenté en partie gauche de la figure 6, ou qui entourent ces verres le long de leur bord supérieur uniquement, comme représenté en partie droite de la figure 6.The embodiment variant represented in Figures 6 to 8 has the advantage of being universal, that is to say, adaptable to all types of frames, including thick plastic mounts. In this variant embodiment, the bridge 10 is substantially rectilinear shape and extends at the level of top edge of the glasses 22 or slightly above from this upper edge, and is connected to branches side 12 surrounding the glasses 22 on substantially half of their periphery, on the outside or opposite side of the bridge 10 as shown on the left-hand side of Figure 6, or surround these glasses along their upper edge only, as shown on the right-hand side of the figure 6.

Dans le premier cas, les branches latérales 12 comportent, de moulage, des crochets 14 de fixation du dispositif sur une monture de lunettes, par exemple deux crochets 14 aux extrémités d'une branche latérale 12 et un troisième crochet sensiblement au milieu de cette branche.In the first case, the lateral branches 12 comprise, of molding, fastening hooks 14 the device on a spectacle frame, by example two hooks 14 at the ends of a branch 12 and a third hook substantially at middle of this branch.

Comme dans le mode de réalisation précédent, les extrémités de chaque branche latérale 12 sont réunies par un fil de nylon qui entoure le restant de la périphérie du verre 22 et est logé dans une rainure périphérique du verre. As in the previous embodiment, the ends of each side branch 12 are joined by a nylon thread that surrounds the rest of the periphery of the glass 22 and is housed in a groove peripheral of the glass.

Lorsque les branches latérales 12 s'étendent uniquement le long du bord supérieur des verres 22 comme représenté en partie droite de la figure 6, ces branches portent chacune deux crochets 14, à leurs extrémités, et un troisième crochet 14 est monté sur le fil de nylon qui enserre le verre 22 entre les extrémités de la branche latérale 12.When the lateral branches 12 extend only along the top edge of the glasses 22 as shown in the right-hand part of Figure 6, these branches each carry two hooks 14, at their ends, and a third hook 14 is mounted on the nylon thread that encloses the glass 22 between extremities of the lateral branch 12.

Dans ce cas, et comme on le voit mieux aux figures 7 et 8, le crochet 14 comprend une partie en U 24 qui est montée à cheval sur le bord du verre 22 et qui comporte deux orifices 26 de passage du fil de nylon 28 monté dans la rainure périphérique du verre 22. Ainsi, le crochet 14 est coulissant sur le fil de nylon 28 et peut être déplacé, par rapport aux deux autres crochets 14 solidaires de la branche latérale 12, pour être amené dans une position de fixation optimale du dispositif sur la monture des lunettes.In this case, and as we see best at FIGS. 7 and 8, the hook 14 comprises a portion U 24 riding on the edge of the glass 22 and which has two orifices 26 for passing the wire of nylon 28 mounted in the peripheral groove of the glass 22. Thus, the hook 14 is sliding on the wire of nylon 28 and can be moved, relative to both other hooks 14 integral with the lateral branch 12, to be brought into a fixing position optimal device on the frame of the glasses.

Dans cette réalisation, le crochet proprement dit est formé d'un doigt incurvé 30 s'étendant depuis la partie en U 24, de façon sensiblement perpendiculaire au verre 22 ou légèrement en oblique par rapport à celui-ci.In this embodiment, the hook properly said is formed of a curved finger 30 extending since the U-shaped part 24, substantially perpendicular to the glass 22 or slightly oblique in relation to this one.

Bien entendu, d'autres moyens de montage des crochets 14 sur les fils de nylon 28 peuvent être utilisés : par exemple, les parties 24 des crochets 14 peuvent comprendre un seul trou parallèle à la périphérie du verre 22 pour le passage du fil 28.Of course, other means of mounting the hooks 14 on 28 nylon threads can be used: for example, parts 24 of the brackets 14 can include a single hole parallel to the periphery of the glass 22 for the passage of the wire 28.

Pour le reste, la variante de réalisation des figures 6 à 8 présente les mêmes caractéristiques que le mode de réalisation des figures 1 à 5, c'est-à-dire que le pont 10 est réalisé d'une seule pièce avec les branches latérales 12 et les crochets 14 prévus sur ces branches latérales, par moulage de matière plastique ou de métal, et les branches latérales 12 présentent sur leur face interne des saillies 16 destinées à être engagées dans les rainures périphériques des verres 22.For the rest, the variant embodiment of the FIGS. 6 to 8 show the same characteristics as the embodiment of Figures 1 to 5, that is to say that the bridge 10 is made in one piece with the side branches 12 and the hooks 14 provided on these lateral branches, by molding of plastic or metal material, and branches side 12 have on their inner face projections 16 intended to be engaged in the peripheral grooves of the glasses 22.

Le dispositif selon l'invention est utilisable pour le montage de verres filtrants de protection solaire sur des lunettes à verres correcteurs, mais il est également utilisable pour le montage de verres correcteurs supplémentaires sur des lunettes, par exemple pour améliorer la vision de près ou la vision nocturne.The device according to the invention is usable for mounting protective filter lenses solar on corrective glasses but it can also be used for mounting lenses additional correctors on glasses, by example to improve near vision or vision night.
